Anti-caries, anti-calculus oral composition, such as dental cream or gel or mouthwash, containing a diamine tetra (methylene phosphonic acid) salt, such as ethylene diamine tetra (methylene polyphosphonic acid) salt, and alkali metal fluoride, such as sodium fluoride. The mole ratio of the tetra (methylene phosphonate) portion to fluoride is at least 1.4:1, thereby providing optimum anti-caries and anti-calculus effects. |
